OK, I am using these words carefully, but do believe this is a true p.r.i.c.e. m.i.s.t.a.k.e. (don't want to set off a bunch of peoples alerts!)
Stopped into Lowe's yesterday for a couple of items and saw this one by chance. Grabbed 3 cans for home use.
Dow Great Stuff Pro GREAT STUFF PRO Gaps and Cracks 24-oz Spray Foam Insulation $2.40 each
All others of this size are in the $12 - $15 range each. Think someone might of missed the 1.
This product does also require the foam gun for use and don't forget the yellow can cleaner!
ONLY BUY AS MUCH AS YOU CAN USE IN THE NEXT 12 MONTHS OR LESS. This product does not store well for long periods of time.
EDIT: Oddly enough, online shows that this item is not available in my state, but bought it in store yesterday.
